GAF FeltBuster Synthetic Roofing Underlayment Roll (1000 sq. ft.)

Upgrade from traditional asphalt felts with the superior protection and performance of FeltBuster® Synthetic Roofing Underlayment, available now at A+ Roofing Supply. As a cost-effective and durable solution, FeltBuster is designed to serve as a secondary layer of defense against wind-driven rain and moisture intrusion—making it a trusted part of the GAF Lifetime Roofing System.

This high-performance underlayment features a tough, tear-resistant polypropylene construction that won’t absorb moisture, become brittle, or leach oils—unlike standard felt. It also lies flatter on the roof deck, reducing unsightly wrinkles and preventing telegraphing through your shingles for a cleaner finished look.

With a medium-gray surface that stays up to 30° cooler than black asphalt felts, it’s also safer and more comfortable for installers working under the sun. Each roll covers 1,000 sq. ft., is super lightweight, and comes in a wider 48-inch format, making handling and application easier than ever.

Eligible for GAF’s Lifetime Limited Warranty when installed with Lifetime Shingles, FeltBuster has earned the Good Housekeeping Seal—a mark of its reliability and performance.
